Dirty Little Tartan

Dirty Little Tartan - student project

What a fun class! I'm noticing that my pattern has a slight white line along some of it, I will have to try again to see if I can rectify that...

Also when I saved it and opened it up again, I could see just how dirty/warn/fabriky I made it... It's a little grunge.

See that white line? Anyone know how to fix it?
